Input string is a stream of ASCII + characters terminated with a null-character ('\0'). Checking it using C language is + difficult and hard to implement without bugs. It is hard to maintain and make changes when + the syntax changes. + + This is because of a high redundancy of the C code. Large blocks of code are duplicated with + only small changes. Even use of macros does not solve the problem because macros cannot + erase the complexity of the problem. + + The resolution is to create a new language that will be highly oriented to our task. Once + we describe a particular syntax, we are done. We can then focus on the code that implements + the language. The size and complexity of it is relatively small than the code that directly + checks the syntax. + + First, we must implement our new language. Here, the language is implemented in C, but it + could also be implemented in any other language. The code is listed below. We must take + a good care that it is bug free. This is simple because the code is simple and clean. + + Next, we must describe the syntax of our new language in itself. Once created and checked + manually that it is correct, we can use it to check another scripts. + + Note that our new language loading code does not have to check the syntax. It is because we + assume that the script describing itself is correct, and other scripts can be syntactically + checked by the former script. The loading code must only do semantic checking which leads us to + simple resolving references. + + THE LANGUAGE + ------------ + + Here I will describe the syntax of the new language (further called "Synek"). It is mainly a + sequence of declarations terminated by a semicolon. The declaration consists of a symbol, + which is an identifier, and its definition. A definition is in turn a sequence of specifiers + connected with ".and" or ".or" operator. These operators cannot be mixed together in a one + definition. Specifier can be a symbol, string, character, character range or a special + keyword ".true" or ".false". + + On the very beginning of the script there is a declaration of a root symbol and is in the form: + .syntax <root_symbol>; + The <root_symbol> must be on of the symbols in declaration sequence. The syntax is correct if + the root symbol evaluates to true. A symbol evaluates to true if the definition associated with + the symbol evaluates to true. Definition evaluation depends on the operator used to connect + specifiers in the definition. If ".and" operator is used, definition evaluates to true if and + only if all the specifiers evaluate to true. If ".or" operator is used, definition evalutes to + true if any of the specifiers evaluates to true. If definition contains only one specifier, + it is evaluated as if it was connected with ".true" keyword by ".and" operator. + + If specifier is a ".true" keyword, it always evaluates to true. + + If specifier is a ".false" keyword, it always evaluates to false. Specifier evaluates to false + when it does not evaluate to true. + + Character range specifier is in the form: + '<first_character>' - '<second_character>' + If specifier is a character range, it evaluates to true if character in the stream is greater + or equal to <first_character> and less or equal to <second_character>. In that situation + the stream pointer is advanced to point to next character in the stream. All C-style escape + sequences are supported although trigraph sequences are not. The comparisions are performed + on 8-bit unsigned integers. + + Character specifier is in the form: + '<single_character>' + It evaluates to true if the following character range specifier evaluates to true: + '<single_character>' - '<single_character>' + + String specifier is in the form: + "<string>" + Let N be the number of characters in <string>. Let <string>[i] designate i-th character in + <string>. Then the string specifier evaluates to true if and only if for i in the range [0, N) + the following character specifier evaluates to true: + '<string>[i]' + If <string>[i] is a quotation mark, '<string>[i]' is replaced with '\<string>[i]'. + + Symbol specifier can be optionally preceded by a ".loop" keyword in the form: + .loop <symbol> (1) + where <symbol> is defined as follows: + <symbol> <definition>; (2) + Construction (1) is replaced by the following code: + <symbol$1> + and declaration (2) is replaced by the following: + <symbol$1> <symbol$2> .or .true; + <symbol$2> <symbol> .and <symbol$1>; + <symbol> <definition>; + + Synek supports also a register mechanizm. User can, in its SYN file, declare a number of + registers that can be accessed in the syn body. Each reg has its name and a default value. + The register is one byte wide. The C code can change the default value by calling + grammar_set_reg8() with grammar id, register name and a new value. As we know, each rule is + a sequence of specifiers joined with .and or .or operator. And now each specifier can be + prefixed with a condition expression in a form ".if (<reg_name> <operator> <hex_literal>)" + where <operator> can be == or !=. If the condition evaluates to false, the specifier + evaluates to .false. Otherwise it evalutes to the specifier. + + ESCAPE SEQUENCES + ---------------- + + Synek supports all escape sequences in character specifiers. The mapping table is listed below. + All occurences of the characters in the first column are replaced with the corresponding + character in the second column. + + Escape sequence Represents + ------------------------------------------------------------------------------------------------ + \a Bell (alert) + \b Backspace + \f Formfeed + \n New line + \r Carriage return + \t Horizontal tab + \v Vertical tab + \' Single quotation mark + \" Double quotation mark + \\ Backslash + \? Literal question mark + \ooo ASCII character in octal notation + \xhhh ASCII character in hexadecimal notation + ------------------------------------------------------------------------------------------------ + + RAISING ERRORS + -------------- + + Any specifier can be followed by a special construction that is executed when the specifier + evaluates to false. The construction is in the form: + .error <ERROR_TEXT> + <ERROR_TEXT> is an identifier declared earlier by error text declaration. The declaration is + in the form: + .errtext <ERROR_TEXT> "<error_desc>" + When specifier evaluates to false and this construction is present, parsing is stopped + immediately and <error_desc> is returned as a result of parsing. The error position is also + returned and it is meant as an offset from the beggining of the stream to the character that + was valid so far. Example: + + (**** syntax script ****) + + .syntax program; + .errtext MISSING_SEMICOLON "missing ';'" + program declaration .and .loop space .and ';' .error MISSING_SEMICOLON .and + .loop space .and '\0'; + declaration "declare" .and .loop space .and identifier; + space ' '; + + (**** sample code ****) + + declare foo , + + In the example above checking the sample code will result in error message "missing ';'" and + error position 12. The sample code is not correct. Note the presence of '\0' specifier to + assure that there is no code after semicolon - only spaces. + <error_desc> can optionally contain identifier surrounded by dollar signs $. In such a case, + the identifier and dollar signs are replaced by a string retrieved by invoking symbol with + the identifier name. The starting position is the error position. The lenght of the resulting + string is the position after invoking the symbol. + + PRODUCTION + ---------- + + Synek not only checks the syntax but it can also produce (emit) bytes associated with specifiers + that evaluate to true. That is, every specifier and optional error construction can be followed + by a number of emit constructions that are in the form: + .emit <parameter> + <paramater> can be a HEX number, identifier, a star * or a dollar $. HEX number is preceded by + 0x or 0X. If <parameter> is an identifier, it must be earlier declared by emit code declaration + in the form: + .emtcode <identifier> <hex_number> + + When given specifier evaluates to true, all emits associated with the specifier are output + in order they were declared. A star means that last-read character should be output instead + of constant value. Example: + + (**** syntax script ****) + + .syntax foobar; + .emtcode WORD_FOO 0x01 + .emtcode WORD_BAR 0x02 + foobar FOO .emit WORD_FOO .or BAR .emit WORD_BAR .or .true .emit 0x00; + FOO "foo" .and SPACE; + BAR "bar" .and SPACE; + SPACE ' ' .or '\0'; + + (**** sample text 1 ****) + + foo + + (**** sample text 2 ****) + + foobar + + For both samples the result will be one-element array. For first sample text it will be + value 1, for second - 0. Note that every text will be accepted because of presence of + .true as an alternative. + + Another example: + + (**** syntax script ****) + + .syntax declaration; + .emtcode VARIABLE 0x01 + declaration "declare" .and .loop space .and + identifier .emit VARIABLE .and (1) + .true .emit 0x00 .and (2) + .loop space .and ';'; + space ' ' .or '\t'; + identifier .loop id_char .emit *; (3) + id_char 'a'-'z' .or 'A'-'Z' .or '_'; + + (**** sample code ****) + + declare fubar; + + In specifier (1) symbol <identifier> is followed by .emit VARIABLE. If it evaluates to + true, VARIABLE constant and then production of the symbol is output. Specifier (2) is used + to terminate the string with null to signal when the string ends. Specifier (3) outputs + all characters that make declared identifier. The result of sample code will be the + following array: + { 1, 'f', 'u', 'b', 'a', 'r', 0 } + + If .emit is followed by dollar $, it means that current position should be output. Current + position is a 32-bit unsigned integer distance from the very beginning of the parsed string to + first character consumed by the specifier associated with the .emit instruction. Current + position is stored in the output buffer in Little-Endian convention (the lowest byte comes + first). +*/ + +static void mem_free (void **); + +/* + internal error messages +*/ +static const byte *OUT_OF_MEMORY = (byte *) "internal error 1001: out of physical memory"; +static const byte *UNRESOLVED_REFERENCE = (byte *) "internal error 1002: unresolved reference '$'"; +static const byte *INVALID_GRAMMAR_ID = (byte *) "internal error 1003: invalid grammar object"; +static const byte *INVALID_REGISTER_NAME = (byte *) "internal error 1004: invalid register name: '$'"; +/*static const byte *DUPLICATE_IDENTIFIER = (byte *) "internal error 1005: identifier '$' already defined";*/ +static const byte *UNREFERENCED_IDENTIFIER =(byte *) "internal error 1006: unreferenced identifier '$'"; + +static const byte *error_message = NULL; /* points to one of the error messages above */ +static byte *error_param = NULL; /* this is inserted into error_message in place of $ */ +static int error_position = -1; + +static byte *unknown = (byte *) "???"; + +static void clear_last_error (void) +{ + /* reset error message */ + error_message = NULL; + + /* free error parameter - if error_param is a "???" don't free it - it's static */ + if (error_param != unknown) + mem_free ((void **) (void *) &error_param); + else + error_param = NULL; + + /* reset error position */ + error_position = -1; +} + +static void set_last_error (const byte *msg, byte *param, int pos) +{ + /* error message can be set only once */ + if (error_message != NULL) + { + mem_free ((void **) (void *) ¶m); + return; + } + + error_message = msg; + + /* if param is NULL, set error_param to unknown ("???") */ + /* note: do not try to strdup the "???" - it may be that we are here because of */ + /* out of memory error so strdup can fail */ + if (param != NULL) + error_param = param; + else + error_param = unknown; + + error_position = pos; +} + +/* + memory management routines +*/ +static void *mem_alloc (size_t size) +{ + void *ptr = grammar_alloc_malloc (size); + if (ptr == NULL) + set_last_error (OUT_OF_MEMORY, NULL, -1); + return ptr; +} + +static void *mem_copy (void *dst, const void *src, size_t size) +{ + return grammar_memory_copy (dst, src, size); +} + +static void mem_free (void **ptr) +{ + grammar_alloc_free (*ptr); + *ptr = NULL; +} + +static void *mem_realloc (void *ptr, size_t old_size, size_t new_size) +{ + void *ptr2 = grammar_alloc_realloc (ptr, old_size, new_size); + if (ptr2 == NULL) + set_last_error (OUT_OF_MEMORY, NULL, -1); + return ptr2; +} + +static byte *str_copy_n (byte *dst, const byte *src, size_t max_len) +{ + return grammar_string_copy_n (dst, src, max_len); +} + +static byte *str_duplicate (const byte *str) +{ + byte *new_str = grammar_string_duplicate (str); + if (new_str == NULL) + set_last_error (OUT_OF_MEMORY, NULL, -1); + return new_str; +} + +static int str_equal (const byte *str1, const byte *str2) +{ + return grammar_string_compare (str1, str2) == 0; +} + +static int str_equal_n (const byte *str1, const byte *str2, unsigned int n) +{ + return grammar_string_compare_n (str1, str2, n) == 0; +} + +static unsigned int str_length (const byte *str) +{ + return grammar_string_length (str); +} + +/* + useful macros +*/ +#define GRAMMAR_IMPLEMENT_LIST_APPEND(_Ty)\ + static void _Ty##_append (_Ty **x, _Ty *nx) {\ + while (*x) x = &(**x).next;\ + *x = nx;\ + } + +/* + string to byte map typedef +*/ +typedef struct map_byte_ +{ + byte *key; + byte data; + struct map_byte_ *next; +} map_byte; + +static void map_byte_create (map_byte **ma) +{ + *ma = (map_byte *) mem_alloc (sizeof (map_byte)); + if (*ma) + { + (**ma).key = NULL; + (**ma).data = '\0'; + (**ma).next = NULL; + } +} + +static void map_byte_destroy (map_byte **ma) +{ + if (*ma) + { + map_byte_destroy (&(**ma).next); + mem_free ((void **) &(**ma).key); + mem_free ((void **) ma); + } +} + +GRAMMAR_IMPLEMENT_LIST_APPEND(map_byte) + +/* + searches the map for the specified key, + returns pointer to the element with the specified key if it exists + returns NULL otherwise +*/ +static map_byte *map_byte_locate (map_byte **ma, const byte *key) +{ + while (*ma) + { + if (str_equal ((**ma).key, key)) + return *ma; + + ma = &(**ma).next; + } + + set_last_error (UNRESOLVED_REFERENCE, str_duplicate (key), -1); + return NULL; +} + +/* + searches the map for specified key, + if the key is matched, *data is filled with data associated with the key, + returns 0 if the key is matched, + returns 1 otherwise +*/ +static int map_byte_find (map_byte **ma, const byte *key, byte *data) +{ + map_byte *found = map_byte_locate (ma, key); + if (found != NULL) + { + *data = found->data; + + return 0; + } + + return 1; +} + +/* + regbyte context typedef + + Each regbyte consists of its name and a default value.

+// Symbol table for parsing. Has these design characteristics:
+//
+// * Same symbol table can be used to compile many shaders, to preserve
+// effort of creating and loading with the large numbers of built-in
+// symbols.
+//
+// * Name mangling will be used to give each function a unique name
+// so that symbol table lookups are never ambiguous. This allows
+// a simpler symbol table structure.
+//
+// * Pushing and popping of scope, so symbol table will really be a stack
+// of symbol tables. Searched from the top, with new inserts going into
+// the top.
+//
+// * Constants: Compile time constant symbols will keep their values
+// in the symbol table. The parser can substitute constants at parse
+// time, including doing constant folding and constant propagation.
+//
+// * No temporaries: Temporaries made from operations (+, --, .xy, etc.)
+// are tracked in the intermediate representation, not the symbol table.

Many of these built-in functions can be used in more than one type +// of shader, but some are intended to provide a direct mapping to hardware and so are available +// only for a specific type of shader. +// +// The built-in functions basically fall into three categories: +// +// * They expose some necessary hardware functionality in a convenient way such as accessing +// a texture map. There is no way in the language for these functions to be emulated by a shader. +// +// * They represent a trivial operation (clamp, mix, etc.) that is very simple for the user +// to write, but they are very common and may have direct hardware support. It is a very hard +// problem for the compiler to map expressions to complex assembler instructions. +// +// * They represent an operation graphics hardware is likely to accelerate at some point. The +// trigonometry functions fall into this category. +// +// Many of the functions are similar to the same named ones in common C libraries, but they support +// vector input as well as the more traditional scalar input. +// +// Applications should be encouraged to use the built-in functions rather than do the equivalent +// computations in their own shader code since the built-in functions are assumed to be optimal +// (e.g., perhaps supported directly in hardware). +// +// User code can replace built-in functions with their own if they choose, by simply re-declaring +// and defining the same name and argument list. +// + +// +// 8.1 Angle and Trigonometry Functions +// +// Function parameters specified as angle are assumed to be in units of radians.

However, level +// of detail is not computed by fixed functionality for vertex shaders, so there are some +// differences in operation between vertex and fragment texture lookups. The functions in the table +// below provide access to textures through samplers, as set up through the OpenGL API. Texture +// properties such as size, pixel format, number of dimensions, filtering method, number of mip-map +// levels, depth comparison, and so on are also defined by OpenGL API calls. Such properties are +// taken into account as the texture is accessed via the built-in functions defined below. +// +// If a non-shadow texture call is made to a sampler that represents a depth texture with depth +// comparisons turned on, then results are undefined. If a shadow texture call is made to a sampler +// that represents a depth texture with depth comparisions turned off, the results are undefined. +// If a shadow texture call is made to a sampler that does not represent a depth texture, then +// results are undefined. +// +// In all functions below, the bias parameter is optional for fragment shaders. The bias parameter +// is not accepted in a vertex shader. For a fragment shader, if bias is present, it is added to +// the calculated level of detail prior to performing the texture access operation. If the bias +// parameter is not provided, then the implementation automatically selects level of detail: +// For a texture that is not mip-mapped, the texture is used directly. If it is mip-mapped and +// running in a fragment shader, the LOD computed by the implementation is used to do the texture +// lookup. If it is mip-mapped and running on the vertex shader, then the base texture is used. +// +// The built-ins suffixed with "Lod" are allowed only in a vertex shader. For the "Lod" functions, +// lod is directly used as the level of detail. +// + +// +// Use the texture coordinate coord to do a texture lookup in the 1D texture currently bound +// to sampler.

+// This file defines nearly all constructors and operators for built-in data types, using
+// extended language syntax. In general, compiler treats constructors and operators as
+// ordinary functions with some exceptions. For example, the language does not allow
+// functions to be called in constant expressions - here the exception is made to allow it.
+//
+// Each implementation provides its own version of this file. Each implementation can define
+// the required set of operators and constructors in its own fashion.
+//
+// The extended language syntax is only present when compiling this file. It is implicitly
+// included at the very beginning of the compiled shader, so no built-in functions can be
+// used.
+//
+// To communicate with the implementation, a special extended "__asm" keyword is used, followed
+// by an instruction name (any valid identifier), a destination variable identifier and a
+// a list of zero or more source variable identifiers. A variable identifier is a variable name
+// declared earlier in the code (as a function parameter, local or global variable).
+// An instruction name designates an instruction that must be exported by the implementation.
+// Each instruction receives data from source variable identifiers and returns data in the
+// destination variable identifier.
+//
+// It is up to the implementation how to define a particular operator or constructor. If it is
+// expected to being used rarely, it can be defined in terms of other operators and constructors,
+// for example:
+//
+// ivec2 __operator + (const ivec2 x, const ivec2 y) {
+// return ivec2 (x[0] + y[0], x[1] + y[1]);
+// }
+//
+// If a particular operator or constructor is expected to be used very often or is an atomic
+// operation (that is, an operation that cannot be expressed in terms of other operations or
+// would create a dependency cycle) it must be defined using one or more __asm constructs.
+//
+// Each implementation must define constructors for all scalar types (bool, float, int).
+// There are 9 scalar-to-scalar constructors (including identity constructors). However,
+// since the language introduces special constructors (like matrix constructor with a single
+// scalar value), implementations must also implement these cases.
+// The compiler provides the following algorithm when resolving a constructor:
+// - try to find a constructor with a prototype matching ours,
+// - if no constructor is found and this is a scalar-to-scalar constructor, raise an error,
+// - if a constructor is found, execute it and return,
+// - count the size of the constructor parameter list - if it is less than the size of
+// our constructor's type, raise an error,
+// - for each parameter in the list do a recursive constructor matching for appropriate
+// scalar fields in the constructed variable,
+//
+// Each implementation must also define a set of operators that deal with built-in data types.
+// There are four kinds of operators:
+// 1) Operators that are implemented only by the compiler: "()" (function call), "," (sequence)
+// and "?:" (selection).
+// 2) Operators that are implemented by the compiler by expressing it in terms of other operators:
+// - "." (field selection) - translated to subscript access,
+// - "&&" (logical and) - translated to "<left_expr> ? <right_expr> : false",
+// - "||" (logical or) - translated to "<left_expr> ? true : <right_expr>",
+// 3) Operators that can be defined by the implementation and if the required prototype is not
+// found, standard behaviour is used:
+// - "==", "!=", "=" (equality, assignment) - compare or assign matching fields one-by-one;
+// note that at least operators for scalar data types must be defined by the implementation
+// to get it work,
+// 4) All other operators not mentioned above. If no required prototype is found, an error is
+// raised. An implementation must follow the language specification to provide all valid
+// operator prototypes.

Fragment shaders output values to the OpenGL pipeline using the built-in +// variables gl_FragColor, gl_FragData and gl_FragDepth, unless the discard keyword is executed. +// +// These variables may be written more than once within a fragment shader. If so, the last value +// assigned is the one used in the subsequent fixed function pipeline. The values written to these +// variables may be read back after writing them. Reading from these variables before writing them +// results in an undefined value. The fixed functionality computed depth for a fragment may be +// obtained by reading gl_FragCoord.z, described below. +// +// Writing to gl_FragColor specifies the fragment color that will be used by the subsequent fixed +// functionality pipeline. If subsequent fixed functionality consumes fragment color and an +// execution of a fragment shader does not write a value to gl_FragColor then the fragment color +// consumed is undefined. +// +// If the frame buffer is configured as a color index buffer then behavior is undefined when using +// a fragment shader. +// +// Writing to gl_FragDepth will establish the depth value for the fragment being processed. If +// depth buffering is enabled, and a shader does not write gl_FragDepth, then the fixed function +// value for depth will be used as the fragment's depth value. If a shader statically assigns +// a value to gl_FragDepth, and there is an execution path through the shader that does not set +// gl_FragDepth, then the value of the fragment's depth may be undefined for executions of the +// shader that take that path. That is, if a shader statically contains a write gl_FragDepth, then +// it is responsible for always writing it. +// +// (A shader contains a static assignment to a variable x if, after pre-processing, the shader +// contains statement that would write x, whether or not run-time flow of control will cause +// that statement to be executed.) +// +// The variable gl_FragData is an array. Writing to gl_FragData[n] specifies the fragment data +// that will be used by the subsequent fixed functionality pipeline for data n. If subsequent +// fixed functionality consumes fragment data and an execution of a fragment shader does not +// write a value to it, then the fragment data consumed is undefined. +// +// If a shader statically assigns a value to gl_FragColor, it may not assign a value to any element +// of gl_FragData. If a shader statically writes a value to any element of gl_FragData, it may not +// assign a value to gl_FragColor. That is, a shader may assign values to either gl_FragColor or +// gl_FragData, but not both. +// +// If a shader executes the discard keyword, the fragment is discarded, and the values of +// gl_FragDepth, gl_FragColor and gl_FragData become irrelevant. +// +// The variable gl_FragCoord is available as a read-only variable from within fragment shaders +// and it holds the window relative coordinates x, y, z, and 1/w values for the fragment. This +// value is the result of the fixed functionality that interpolates primitives after vertex +// processing to generate fragments. The z component is the depth value that would be used for +// the fragment's depth if a shader contained no writes to gl_FragDepth. This is useful for +// invariance if a shader conditionally computes gl_FragDepth but otherwise wants the fixed +// functionality fragment depth. +// +// The fragment shader has access to the read-only built-in variable gl_FrontFacing whose value +// is true if the fragment belongs to a front-facing primitive. One use of this is to emulate +// two-sided lighting by selecting one of two colors calculated by the vertex shader. +// +// The built-in variables that are accessible from a fragment shader are intrinsically given types +// as follows: +// + +__fixed_input vec4 gl_FragCoord; +__fixed_input bool gl_FrontFacing; +__fixed_output vec4 gl_FragColor; +__fixed_output vec4 gl_FragData[gl_MaxDrawBuffers]; +__fixed_output float gl_FragDepth; + +// +// However, they do not behave like variables with no qualifier; their behavior is as described +// above. These built-in variables have global scope. +// + +// +// Unlike user-defined varying variables, the built-in varying variables don't have a strict +// one-to-one correspondence between the vertex language and the fragment language. Two sets are +// provided, one for each language. Their relationship is described below. +// +// The following varying variables are available to read from in a fragment shader. The gl_Color +// and gl_SecondaryColor names are the same names as attributes passed to the vertex shader. +// However, there is no name conflict, because attributes are visible only in vertex shaders +// and the following are only visible in a fragment shader. +// + +varying vec4 gl_Color; +varying vec4 gl_SecondaryColor; +varying vec4 gl_TexCoord[]; // at most will be gl_MaxTextureCoords +varying float gl_FogFragCoord; + +// +// The values in gl_Color and gl_SecondaryColor will be derived automatically by the system from +// gl_FrontColor, gl_BackColor, gl_FrontSecondaryColor, and gl_BackSecondaryColor based on which +// face is visible. If fixed functionality is used for vertex processing, then gl_FogFragCoord will +// either be the z-coordinate of the fragment in eye space, or the interpolation of the fog +// coordinate, as described in section 3.10 of the OpenGL 1.4 Specification. The gl_TexCoord[] +// values are the interpolated gl_TexCoord[] values from a vertex shader or the texture coordinates +// of any fixed pipeline based vertex functionality. +// +// Indices to the fragment shader gl_TexCoord array are as described above in the vertex shader +// text. +// + +// +// The OpenGL Shading Language defines an assortment of built-in convenience functions for scalar +// and vector operations. Many of these built-in functions can be used in more than one type +// of shader, but some are intended to provide a direct mapping to hardware and so are available +// only for a specific type of shader. +// +// The built-in functions basically fall into three categories: +// +// * They expose some necessary hardware functionality in a convenient way such as accessing +// a texture map. There is no way in the language for these functions to be emulated by a shader. +// +// * They represent a trivial operation (clamp, mix, etc.) that is very simple for the user +// to write, but they are very common and may have direct hardware support. It is a very hard +// problem for the compiler to map expressions to complex assembler instructions. +// +// * They represent an operation graphics hardware is likely to accelerate at some point. The +// trigonometry functions fall into this category. +// +// Many of the functions are similar to the same named ones in common C libraries, but they support +// vector input as well as the more traditional scalar input. +// +// Applications should be encouraged to use the built-in functions rather than do the equivalent +// computations in their own shader code since the built-in functions are assumed to be optimal +// (e.g., perhaps supported directly in hardware). +// +// User code can replace built-in functions with their own if they choose, by simply re-declaring +// and defining the same name and argument list. +// + +// +// 8.7 Texture Lookup Functions +// +// Texture lookup functions are available to both vertex and fragment shaders. However, level +// of detail is not computed by fixed functionality for vertex shaders, so there are some +// differences in operation between vertex and fragment texture lookups. The functions in the table +// below provide access to textures through samplers, as set up through the OpenGL API. Texture +// properties such as size, pixel format, number of dimensions, filtering method, number of mip-map +// levels, depth comparison, and so on are also defined by OpenGL API calls. Such properties are +// taken into account as the texture is accessed via the built-in functions defined below. +// +// If a non-shadow texture call is made to a sampler that represents a depth texture with depth +// comparisons turned on, then results are undefined. If a shadow texture call is made to a sampler +// that represents a depth texture with depth comparisions turned off, the results are undefined. +// If a shadow texture call is made to a sampler that does not represent a depth texture, then +// results are undefined. +// +// In all functions below, the bias parameter is optional for fragment shaders. The bias parameter +// is not accepted in a vertex shader. For a fragment shader, if bias is present, it is added to +// the calculated level of detail prior to performing the texture access operation. If the bias +// parameter is not provided, then the implementation automatically selects level of detail: +// For a texture that is not mip-mapped, the texture is used directly. If it is mip-mapped and +// running in a fragment shader, the LOD computed by the implementation is used to do the texture +// lookup. If it is mip-mapped and running on the vertex shader, then the base texture is used. +// +// The built-ins suffixed with "Lod" are allowed only in a vertex shader. For the "Lod" functions, +// lod is directly used as the level of detail. +// + +// +// Use the texture coordinate coord to do a texture lookup in the 1D texture currently bound +// to sampler.

Therefore, +// an OpenGL implementation may approximate the true derivatives by using a fast but not entirely +// accurate derivative computation. +// +// The expected behavior of a derivative is specified using forward/backward differencing. +// +// Forward differencing: +// +// F(x+dx) - F(x) ~ dFdx(x) * dx 1a +// dFdx(x) ~ (F(x+dx) - F(x)) / dx 1b +// +// Backward differencing: +// +// F(x-dx) - F(x) ~ -dFdx(x) * dx 2a +// dFdx(x) ~ (F(x) - F(x-dx)) / dx 2b +// +// With single-sample rasterization, dx <= 1.0 in equations 1b and 2b. For multi-sample +// rasterization, dx < 2.0 in equations 1b and 2b. +// +// dFdy is approximated similarly, with y replacing x. +// +// A GL implementation may use the above or other methods to perform the calculation, subject +// to the following conditions: +// +// 1) The method may use piecewise linear approximations. Such linear approximations imply that +// higher order derivatives, dFdx(dFdx(x)) and above, are undefined. +// +// 2) The method may assume that the function evaluated is continuous. Therefore derivatives within +// the body of a non-uniform conditional are undefined. +// +// 3) The method may differ per fragment, subject to the constraint that the method may vary by +// window coordinates, not screen coordinates. The invariance requirement described in section +// 3.1 of the OpenGL 1.4 specification is relaxed for derivative calculations, because +// the method may be a function of fragment location. +// +// Other properties that are desirable, but not required, are: +// +// 4) Functions should be evaluated within the interior of a primitive (interpolated, not +// extrapolated). +// +// 5) Functions for dFdx should be evaluated while holding y constant. Functions for dFdy should +// be evaluated while holding x constant. However, mixed higher order derivatives, like +// dFdx(dFdy(y)) and dFdy(dFdx(x)) are undefined. +// +// In some implementations, varying degrees of derivative accuracy may be obtained by providing +// GL hints (section 5.6 of the OpenGL 1.4 specification), allowing a user to make an image +// quality versus speed tradeoff. +// + +// +// Returns the derivative in x using local differencing for the input argument p. +// +// XXX +float dFdx (float p) { + return 0.0; +} +// XXX +vec2 dFdx (vec2 p) { + return vec2 (0.0); +} +// XXX +vec3 dFdx (vec3 p) { + return vec3 (0.0); +} +// XXX +vec4 dFdx (vec4 p) { + return vec4 (0.0); +} + +// +// Returns the derivative in y using local differencing for the input argument p. +// +// These two functions are commonly used to estimate the filter width used to anti-alias procedural +// textures.We are assuming that the expression is being evaluated in parallel on a SIMD array so +// that at any given point in time the value of the function is known at the grid points +// represented by the SIMD array.

+/*
+ * usage:
+ * syn2c slang_shader.syn > slang_shader_syn.h
+ *
+ * when modifying or extending this file, several things must be taken into consideration:
+ * - when adding new operators that were marked as reserved in the initial specification,
+ * one must only uncomment particular lines of code that refer to operators being added;
+ * - when adding new shader target, one must reserve new value for shader_type register and
+ * use it in .if constructs for symbols that are exclusive for that shader;
+ * - some symbols mimic output of other symbols - the best example is the "for" construct:
+ * expression "for (foo(); ; bar())" is seen as "for (foo(); true; bar())" by the output
+ * processor - hence, special care must be taken when rearranging output of essential symbols;
+ * - order of single-quoted tokens does matter in alternatives - so do not parse "<" operator
+ * before "<<" and "<<" before "<<=";
+ * - all double-quoted tokens are internally preprocessed to eliminate problems with parsing
+ * strings that are prefixes of other strings, like "sampler1D" and "sampler1DShadow";

The size can be +// at most gl_MaxTextureCoords. Using indexes close to 0 may aid the implementation +// in preserving varying resources. +// + +// +// The OpenGL Shading Language defines an assortment of built-in convenience functions for scalar +// and vector operations. Many of these built-in functions can be used in more than one type +// of shader, but some are intended to provide a direct mapping to hardware and so are available +// only for a specific type of shader. +// +// The built-in functions basically fall into three categories: +// +// * They expose some necessary hardware functionality in a convenient way such as accessing +// a texture map. There is no way in the language for these functions to be emulated by a shader. +// +// * They represent a trivial operation (clamp, mix, etc.) that is very simple for the user +// to write, but they are very common and may have direct hardware support. It is a very hard +// problem for the compiler to map expressions to complex assembler instructions. +// +// * They represent an operation graphics hardware is likely to accelerate at some point. The +// trigonometry functions fall into this category. +// +// Many of the functions are similar to the same named ones in common C libraries, but they support +// vector input as well as the more traditional scalar input. +// +// Applications should be encouraged to use the built-in functions rather than do the equivalent +// computations in their own shader code since the built-in functions are assumed to be optimal +// (e.g., perhaps supported directly in hardware). +// +// User code can replace built-in functions with their own if they choose, by simply re-declaring +// and defining the same name and argument list. +// + +// +// Geometric Functions +// +// These operate on vectors as vectors, not component-wise. +// + +// +// For vertex shaders only. This function will ensure that the incoming vertex value will be +// transformed in a way that produces exactly the same result as would be produced by OpenGL's +// fixed functionality transform. It is intended to be used to compute gl_Position, e.g., +// gl_Position = ftransform() +// This function should be used, for example, when an application is rendering the same geometry in +// separate passes, and one pass uses the fixed functionality path to render and another pass uses +// programmable shaders. +// + +vec4 ftransform () { + return gl_ModelViewProjectionMatrix * gl_Vertex; +} + +// +// 8.7 Texture Lookup Functions +// +// Texture lookup functions are available to both vertex and fragment shaders. However, level +// of detail is not computed by fixed functionality for vertex shaders, so there are some +// differences in operation between vertex and fragment texture lookups. The functions in the table +// below provide access to textures through samplers, as set up through the OpenGL API. Texture +// properties such as size, pixel format, number of dimensions, filtering method, number of mip-map +// levels, depth comparison, and so on are also defined by OpenGL API calls. Such properties are +// taken into account as the texture is accessed via the built-in functions defined below. +// +// If a non-shadow texture call is made to a sampler that represents a depth texture with depth +// comparisons turned on, then results are undefined. If a shadow texture call is made to a sampler +// that represents a depth texture with depth comparisions turned off, the results are undefined. +// If a shadow texture call is made to a sampler that does not represent a depth texture, then +// results are undefined. +// +// In all functions below, the bias parameter is optional for fragment shaders. The bias parameter +// is not accepted in a vertex shader. For a fragment shader, if bias is present, it is added to +// the calculated level of detail prior to performing the texture access operation. If the bias +// parameter is not provided, then the implementation automatically selects level of detail: +// For a texture that is not mip-mapped, the texture is used directly. If it is mip-mapped and +// running in a fragment shader, the LOD computed by the implementation is used to do the texture +// lookup. If it is mip-mapped and running on the vertex shader, then the base texture is used. +// +// The built-ins suffixed with "Lod" are allowed only in a vertex shader.

+ The original TIntermTraverser class that is used to walk the intermediate tree,
+ is not very elegant in its design. One must define static functions with
+ appropriate prototypes, construct TIntermTraverser object, and set its member
+ function pointers to one's static functions. If traversal-specific data
+ is needed, a new class must be derived, and one must up-cast the object
+ passed as a parameter to the static function.
+
+ The class below eliminates this burden by providing virtual methods that are
+ to be overridden in the derived class.
